An Experimental Investigation of Curvature Effect on the Laminated Composites at Low Velocity Impact

The aim of this study is to investigate experimentally effects of curvature, fibre orientation and ageing process on the low velocity impact behaviour of E-glass/epoxy composites. To investigate ageing effect, the half of the specimens have been left to dry at room condition and the other half was aged by the salt spray test. An apparatus was designed and produced to conduce impact tests of curved specimens. 20 J impact energy was used for experiments.
